You've been lost for nearly as long as you can remember—jumping from year to year, from time to time. You never stay for long, and you cannot control when or where you land.
One day, after being thrown from ancient Greece to the Roaring 20s in America, you find yourself stuck. You're unsure what's changed or how long this reprieve will last. Then, you meet him. He's handsome and charming. Weeks turn into months. He tells you that he loves you, and you realize that, for the first time, you are in love.
This must be why you've been lost in time: You were looking for him all along. You tell him as much. You fall asleep in his arms. When you wake up, you are in 1670 Russia.
You don't know how, but you know you must make it back to your love, whatever the cost.
